错误:Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:3.1:
解决方法:
1.在你自己版本的maven下的conf文件中修改settings文件,我的是在F:\app\Maven\apache-maven-3.2.3\conf
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

本地仓库被注释掉了。
2.在你的maven库中的里面的setting中修改设置。
3.在eclipse中的window的preferences的maven的User Settings中设置Maven的路径,
这个选项是对应的刚才没有注释本地路径的那个settings文件,不是conf的settings文件。然后点击update settings按钮
4.对项目进行maven->update project就可以了。
